Application filed. May 9, 1913. Serial No. 766,631.

To all whom it may 007106! a Be it known that I, KIoI-IrrAno TANAKA,residing at No. 2 Furuishiba Machi, Fukagawa Ku, city of Tokyo, Empireof Japan, have invented certain new and useful Improvements inLife-Preservers at Sea, of which the following is the specification.

This invention relates to a life saving apparatus which consists of anoblong floating bag, at the middle part of which is attached anotherfloating bag of square or nearly square form, the whole forming acomplex bag with three chambers.

The apparatus has a hole at the central part for the neck so that it canbe fastened upon the shoulders.

The object of the invention is, by proper distribution of floatingcapacity among various chambers, to make the center of gravity lie belowthe shoulders of the wearer, and to enable him to keep his head abovewater, thus making it easy for him to swim and save his life.

In the accompanying drawing, Figure 1 is a plan of the apparatus; andFigs. 2 and 3 are respectively a front and a back view of the apparatusinflated with air.

The same numbers refer to the same parts throughout all the figures.

This invention is made of suitable material in the form of a complex bagand is inflated with the air. (1) and (2) are the main body of the bagof which the middle part is to rest upon the shoulders, and they are tobe tied (1) upon the breast and (2) upon the back. In order to make iteasy to keep the upper part of the body above water, another square ornearly square bag (3) is attached to the main bag; and the proportionsof the capacity of the several chambers (1), (2) and (3) arerespectively a, 2 and 6.

(5) isapipe for blowing in the air, (6) (6) Copies of this patent may beobtained for five cents each, by addressing are bands to tie theapparatus around the body, and (7) (7) are rings to pass the bands,while (8) is a pocket to put in the free end of the pipe (5) when not inuse.

This apparatus can be used not only as a life prcserver but also as apillow or a cushion.

Having now fully described my invention and the manner of carrying thesame into ell'ect, what I claim as new and desire to secure by LettersPatent, is-

1. In a device of the character described; a main air chamber, adaptedto be worn on the breast of the wearer; a secondary chamber integraltherewith and adapted to be placed on the back of the wearer; anauxiliary air chamber integral with the main chamber and adapted to itabout the neck and the back of the head of the wearer; inflating means;securing means; and means for preventing the inflating means frominterfering with the movements of the wearer.

2. In a device of the character described,

a main air chamber, adapted to be worn on the breast of the wearer; asecondary chamber integral therewith and adapted to be placed on theback of the wearer; an auxiliary chamber integral with the main chamberand adapted to be fitted about the neck and the back of the wearer; thesaid chambers being in the proportions of 4, 2, and 6, respectively;inflating means; securing means; and means for preventing the inflatingmeans from interfering with the movements of the wearer.
